Specification of Letters Patent.

Fatented May 5, 131er.

original application led May 28, 1913, Serial No. 770,460. Divided and. this application filed August 14,

To @ZZ whom, t may concern Bc it known that l, VILLIAM Ban'rHoLonew, a. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gudgeons, of which the following is a specification, reference beinO' had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in trunnion construction for knock-down washing cylinders and comprises a division of my application for knock-down renewable washing cylinder, filed May 2S, 1913, Serial Number 770,460; the object being to provide novel means for connecting the trunnion plate to the head, whereby the same can be easily and quickly attached or detached; said members having cooperating portions in order to prevent the same from moving after being placed in position.

Another1 and further object of the invention is to provide a trunnion plate with conical projections which extend into sockets formed in the head which are provided with threaded bores to receive a machine screw which ext-ends through the projection so as to force the same into the sockets and securely lock the same therein.

Another object of the invention is to provide a washing cylinder which is exceedingly simple and cheap in construction; the head being formed with a hub having spokes carrying the ribs and staves of the washing cylinder and to which the trunnion is detachably connected.

Other and further objects and advantages of the invention will be hereinafter setr forth and the novel features thereof defined by the appended claims.

1n the drawings- Figure 1, is a perspective of a washing cylinder showing the arrangement of the trunnion plate upon the head; Fig. 2, is a vertical longitudinal section through a portion of the cylinder showing the manner of fasteningthe trunnion plate in positoin; 3, is a detail plan view of a. portion of the hub of a washing cylinder head, showing the sockets; and Fig. 4, is a detail section through one of the sockets and projections of the trunnion plate showing the bolt in position for securing the projections within the sockets.

Serial No. 784,743.

Like numerals of reference refer to like parts in the several gures-of the drawings.

In the drawing, 1 indicates a washing cylinder which is provided with head members carrying the staves as clearly set forth in the original application; said head members being provided with hub portions 2 from which radiate spokes 3 preferably channeled and provided with rib sockets 1 at v their ends; said spokes being connected together by a rim 5 upon which the staves are mount; ed and the rim between one pair of spokes is enlarged as shown ato provided with aV centrai inset portion forming one member of the hoop tightener as fully described in my former application; the adjacent side portion of the enlarged portion forming a support for the hoop 7. The hub portion is provided with spaced sockets 8 preferablycylindrical in shape having a central threaded bore formed in their bottoms for the purpose later described;

The skeleton trunnion plate 10' of substantially the same diameter as the hub, is arranged against the outer face thereof and is formed with spaced conical projections 11 adapted to fit within the sockets 8 of the Vhub and said projections are provided with bor-es 12 through which machines bolts 13 are adapted to pass into the threaded bores 9 of the sockets so as to draw the projections into the sockets in such a manner that a wedging eect will be obtained in order to prevent the same from moving in any direction, whereby the trunnion plate will be fixed firmly to the head in such a manner that the same can be easily and quickly attached or detached.

lt will be seen thatr by providing the trunnion plate with these projections which eX- tend into the sockets of the head, that the strain on the bolts 13 is relieved; the bolts serving the purpose of fastening the projec-L tions into the sockets and as the strain is axially, the bolts are not subject-ed to any stress and, therefore, the connection is such that an exceedingly strong and durable means is provided for connecting the trunnion plateto the head. The trunnion plate 10 is provided with a central hub portion 14 in which thetrunnion 15 is mounted by any suitable means, v

The construction of washing cylinder including the ribs, sta-ves and manner of fastening` the saine in position upon the rini of the head is clearly shown in the original application and the inanner of placing the head plates in order to forni a tight joint between the stares, ribs and head is also clearly described and illustrated in the original application and it is not necessary te go into detail in connection with this invention.

Frein the foregoing description, it vill be seen that have provided a trunnion ccnstruction for a renewable knock-down washing cylinder which is so constructed that when placed in position, it will be securelT fastened upon the head and when power is applied to one of the trunnions, the cylinder will be rotated in such a manner as to prevent any danger of the saine beingl twisted oit'.

I claiin:

1. A trunnion connection, comprising a member having a hub portion provided with spaced circular sockets having central threaded bores7 a trunnion plate arranged upon said hub provided with spaced apertured conical projections extending into said sockets and bolts extending through the bores of said projections into the threaded bores of said sockets for securing said trunnien plate in position thereon.

As a new article of manufacture, a head nieinber having a hub portion provided with spaced cylindrical sockets having centrally arranged threaded bores, a trunnion plate having,` spaced conical apertured prejectio-ns extending into said sockets1 and threaded members passing through the apertures of said projections working in the threaded bores of said sockets for securing said head ineniber and plate together.
